N9NE

N9NE has very simple rules however it can be a very challenging game. One to 4 players place the 9 numbers from 1 to 9, in 9 series, on a 9x9 board to obtain sums of adjacent numbers (horizontally, vertically or diagonally) that equal 9 or multiples of 9.

Objective:
Make sequences of numbers from 1 to 9 so that their sum (horizontally, vertically or diagonally) is 9 or a multiple of 9.

Points:
Sum ≠ multiple of 9 = -1 Point; 9 = 0 Points; 18 = 1 Point; 27 = 3 Points; 36 = 9 Points; 45, 54, 63... = Wins Immediately.

Rules:
Each player (in their turn) selects a number from 1 to 9 and places it in an empty square on the board to try to obtain a sequence that adds 9 or a multiple of 9;
The sum is valid either horizontally, vertically or diagonally. On the same turn a player can do more than one multiple simultaneously;
The filled squares and already used on previous sums can be used in new sums only if in a different direction;
The filled squares and already used on previous sums cannot be used in new sums if these are extensions or overlays;
A player is allowed to make bridges, meaning, get a sum of 9 or multiple of 9 going over used squares in the same direction, as if these squares didn’t exist.";
During the game, each play has one single help that can be used when he wants;
The game is over when all the squares are filled or when one player gets a sum of 45 or a higher multiple of 9;

Now its time to start playing. Are you ready to be a N9NEs master? Good calculations!
